Exact-match server upgrade

This NEMIX RAM kit provides 1.5 TB of DDR5 capacity across twelve 128 GB registered ECC modules. It is built for administrators expanding a Supermicro H13SSW motherboard to its full memory ceiling. The 2Rx4 organization and 1.10 V operation match the board's native memory-controller expectations.

Sustained-load stability

Registered buffering offloads the memory controller so all twelve slots run fully populated at the rated 4800 MT/s without throttling. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during continuous compute or database workloads. The CL40 timing is maintained across the full kit under prolonged thermal stress.

Twelve-module population rule

The H13SSW requires a specific 12 x 128 GB population order to recognise the full 1.5 TB at DDR5-4800. Builders who cannot populate all twelve slots in the prescribed sequence will not achieve the rated capacity or speed.

Questions about this item

How much heat does the 1.1V DDR5-4800 CL40 2Rx4 registered kit generate when running all day?

Each 128 GB module operates at 1.10 V DDR5 standard voltage. Registered buffering and the absence of a heat spreader mean thermal output is in line with typical enterprise RDIMMs; ensure your server chassis provides the airflow the motherboard manual specifies.

What motherboard and CPU combination must I already own for this 1.5 TB 12×128 GB kit to work?

The kit is validated for the Supermicro H13SSW motherboard. You need that board with a compatible processor that supports 12 DDR5 RDIMM slots, registered ECC memory, and 2Rx4 population rules at DDR5-4800.

Can I keep existing DDR5 RDIMMs of different capacity or rank in the other slots of the H13SSW while adding this 2Rx4 128 GB kit?

The H13SSW requires matched population per channel. Mixing ranks or capacities can prevent full-speed operation or cause the system to down-clock; consult the board manual for approved DIMM configurations before mixing.
